The third time I used the fins the pull strap broke.  If this only happened to me I'd say it was an anomaly, however the same thing happened to a friend shortly after buying his fins.  Will I recommend Zip Fins to others, probably not!

I do laps for one hour and wearing the Zip Fins really gives my legs a good work out!  I've tried other kinds of fins but these are perfect and it doesn't hurt my knees.  The good thing about these fins too is the straps are adjustable so you don't have to worry about them slipping off.

Aqua Shere puts out a good product, I use Zip Fins every day  to keep my leg muscles and knees in shape.  The straps break over time but on the last pair before this one, they remained intact.

these fins are great as this my second pair . the first pair lasted 3 years of use  two to three tines a week

GREAT PRODUCT IS EASY TO WORK WITH IT , THE SUPPORT IN THE BACK IS PERFECT SMOOTH, AND SOFT, IS PERFECT FOR PEOPLE WITH NARROW FEET

My old pair (at least 10 years old) finally bit the dust and I was fearful I wouldn't find a replacement.  SwimOutlet had them and they are exactly the same--GREAT.  I swim daily (often 2X) and these flippers have really made me a stronger swimmer.  I forget I even have the on at times.  I'm glad I found them on SwimOutlet and at a very reasonable price as well.  Thanks!
